Beavis and Butt-Head

Serena Ryan is a former astronaut of NASA and governor of Texas who appears as the main antagonist in Beavis and Butt-Head Do the Universe.

She is voiced by Andrea Savage.


Serena is a tall and attractive tan-skinned woman with brown hair that is parted to the left side, brown eyes and she has a slim build.

Her hair changes in the film with it being long in the past and bobbed in the present.


In 1998, Serena's hair reached her middle back where she mostly leaves it down and she later ties it up in a ponytail upon going into space.

She was seen wearing a blue NASA jumpsuit and later an orange spacesuit.


By 2022, Serena cuts her hair to shoulder-length and she has a few more lines on her face.

She wears small silver hoop earrings, a gold necklace, a blue tailored business suit with a white blouse, brown boots and red nail polish.


Serena is shown to have a headstrong and somewhat erratic personality. While intelligent enough to become an astronaut and eventual governor, she (like many other characters) was oblivious to Beavis and Butt-Head's stupidity and horniness until the end of the movie.

She is dedicated to her work to a near-obsessive degree, said to have dreamed of being astronaut since childhood and shown to do whatever it takes to preserve her reputation/career; she is willing to sacrifice herself for her crew and later is willing to break laws to ensure her re-election. She even considers having sex with Beavis and Butt-Head to keep her misdeeds hidden if she must.

She is vindictive towards Beavis and Butt-Head for their idiocy dooming the mission in space (forcing her to suffer for weeks, drinking her urine and even resorting to cannibalism to survive), trying to kill them and cover it up, then trying to kill them again 24 years later when she finds out they survived and assumes they want revenge. However, once she realizes her error, she seems to have no ill will towards them.

She practically demands respect from others, acting dismissive towards her assistant for decades and immediately agreeing to hook up with Smart Beavis after he praised her and offered her everything she wanted, but she likely did not enjoy the experience seeing as she ignored Smart Beavis' calls after having sex with him.


  • Serena very much resembles her voice actress Andrea Savage.
  • Serena fills a very similar niche to Dallas Grimes from the Beavis and Butt-Head Do America movie, particularly with the boys' desire to "score" with Serena driving the plot of the Beavis and Butt-Head Do the Universe movie, much like with their attraction to Dallas in the first movie, but ends up being a very different kind of antagonist. However, Serena and Dallas have very different characteristics from each other:
    • Dress-wise, Dallas tends to wear more skimpy clothing while Serena dresses more modestly by comparison.
    • While Dallas was an open criminal and terrorist, Serena managed to lead a more legit political career and whatever corrupt, criminal things she did were done in secrecy without exposure.
    • Dallas was openly hostile to Beavis and Butt-Head to begin with and despite acting seductive to get what she wanted out of them, she had no intention of ever "scoring" with them. On the other hand, Serena is actually genuinely friendly with the boys to begin with and despite growing more hostile to them throughout the movie, she eventually gives up on that hostility and consents to their desires, albeit with some small reluctance.
